Am having trouble upgrading MyPBX U100 firmware (184.108.40.206.bin, 220.127.116.11.bin, 18.104.22.168.bin) using the TFTP method. The trouble I had is that after upgrading myPBX U100, it returns back to upgrade page stating (The hardware is not match to your current firmware version. Upgrade cannot be completed)..
Please help find a solution for this problem.. Waiting for you swift response.
